"She felt [Kensington] had an overriding musty, damp smell, and ordered a six-month supply of her favorite products to override this. She’s also thrown pillows around to make it look more minimalist-chic and less fuddy-duddy. William was happy to go with the flow."

Designer Hoppen has also been tapped to redesign and modernize the pair's new quarters.
